Hi mechko,

frame.redraw() might not work, try

Code: Select all

frame.forceRedraw()

It does work, I tried with the simple demos shipped with jfreechart. for instance with SWTTimeSeriesDemo I get: Rectangle {59, 31, 521, 170}

There is something wrong in your code, you do not need the ChartPanel instance :

Code: Select all

final ChartComposite frame = new ChartComposite(parent, SWT.NONE,chart, true);
frame.setPopupMenu(null);

Hi Martin,

which version of the code are you using? I've been out of the loop for a couple of months now being overcommited elsewhere. I think the last code from svn is fine, being basically very similar to your suggestion. Comments are welcome, thanks again.

Hi, this problem is now fixed in the svn tree. Will be in jfreechart 1.10.

Thanks for your feedback.

seems to be a problem with java 6 on windows. No problem for me on Linux both with 1.5 and 1.6 so I cannot help much here...

Thanks for the comments, I've updated the SWTGraphics2D with a new pool for transform objects and ChartComposite with some fixes too.

mmh, I do not see exactly what you're saying but I can tell there is a problem. Here if you move the mouse on entities fast enough so that the previous tooltip do not disappear, the old one is replaced by the new one without updating the location. In short the tooltip is misplaced. I remember when I...

Thanks,
I've no experience with OSGI so cannot really comment here except that we do not have an OSGI bundle of jfree.

to compile the swt code, you need version 3.2 of the SWT library.
The pre-compiled jar will work on any plateform supported by SWT but need to be linked with SWT>=3.2

Hum not ChartProgressEvents, you need to subclass ChartComposite and override the chartProgress method (just like the with ChartPanel class):

Code: Select all

    public void chartProgress(ChartProgressEvent event) {
        // does nothing - override if necessary
    }

I don't think Cpu usage is a good indicator of performance. You'd better measure system time in ms before and after drawing processes. And you should measure it not only for one draw but for hundreds or perhaps a thousand draw operations to avoid scattering.

Hi Kenzo, It's not decided yet but I think the experimental SWT branch will be in the moved in the main tree in jfreechart 1.2.0. Regarding your second question, it's not very clear to me what you're asking. The experimental code already do that (you do not need the method SWT_AWT.new_Frame). It's q...

Hi Raghavan, This behaviour is not ideal since to draw the chart the bounds of the composite are used and do not take into account the scroll bar. Thus the bottom part of the chart is masked. I'm considering to switch to a Canvas instead of Composite as suggested by someone on this forum. in the mea...

Hi Andrea,

Could you maybe post a screenshot of what's wrong? I'm developping with linux and I do not see anything abvious here. I'll have a deeper look when I get some time (pretty overbooked these days).
